I replaced the cracked screen on my iPhone 2g and synced it before changing it. Everything was working fine, when i tried to charge the phone and sync my computer wouldnt recognize it.

It won't charge through my wall chargers either ive tried 2 of them. The wierd thing is my apple hi-fi stereo system when i dock my iphone it recognizes it and i can hear the clicks of the phone through the speakers. It says "this device is not made for this...turn on airplane mode" But the phones charging symbols are on.

What is the problem? I tried different cords but i get no response from the computer. Its running 3.1.3 unlocked/jb.

I tried to open it up and reconnect it twice now, but it seems its as in as far as it will go and i have clicked the black snap down on it properly. Plus it wouldnt charge through my hi-fi if it wasnt in properly right?

Thats what stumps me, it charges and plays sound through the dock on the speakers but doesnt charge or recognize any other cord/dock.

Guess i left it out that i tried many different cords, and wall chargers and tried two different comps. Won't recognize any and doesnt show up in my comp as a mass storage device either so its not just itunes.

Yea i came to the same conclusion, ive tried wiggling it on both the usb and iphone dock side. Wont chirp or recognize it at all. I was wondering if the hi-fi stereo charges it a different way perhaps? Im not sure cause i dont have to wiggle it at all on that, it just charges and recognizes the stereo immediately.
